The earbud 100 includes an upper portion 102, a base portion 104 and anear interface portion 106. During use, the ear interface portion 106 isplaced within or proximate to the ear of a user. The upper portion 102typically includes an audio output speaker that produces audible soundthat is provided to the user's ear via the ear interface portion 106.The base portion 104 supports the upper portion 102 and typicallycouples the earbud 102 to a cord 108. In addition, the earbud 100 caninclude an activity sensor 110 integrated with the earbud 100. Asillustrated in FIG. 1A, the activity sensor 110 can be integrated withthe upper portion 102 of the earbud 100. However, it should be notedthat in an alternative embodiment, the activity sensor 110 can beembedded in the base portion 104 of the earbud 100. In one embodiment,the activity sensor 110 includes at least an accelerometer. In anotherembodiment, the activity sensor 110 can include a plurality ofaccelerometers, each pertaining to a different axis.

FIG. 1B is an exemplary diagram of a cord-based monitoring system 120according to one embodiment of the invention. The cord-based monitoringsystem 120 can be utilized by headphones, earbuds or headsets thatutilize a cord. The cord-based monitoring system 120 can include asensor housing 122 attached to a cord 124. The sensor housing 122 caninclude the activity sensor 110. Here, the activity sensor 110 isattached to the cord 124, as opposed to being integrated with the earbud100 as illustrated in FIG. 1A. Optionally, the cord-based monitoringsystem 120 can include a user input device 126. For example, the userinput device 126 can pertain to a button.

The cord-based monitoring system 120 can also include a securing meansfor securing the cord-based monitoring system 120 to a user's body orclothing. Examples of securing means include Velcro™ (hook and loops),button, pocket, strap, clip, etc.

FIG. 1C is an exemplary diagram of an ear-based monitoring system 140according to one embodiment of the invention. The ear-based monitoringsystem 140 includes an earbud 142 having a base portion 144. Anattachment member 146 can couple to the base portion 144. The attachmentmember 146 physically attaches a sensor housing 148 to a locationproximate to the user's ear. The sensor housing 148 can include theactivity sensor 110. In this embodiment, the activity sensor 110 ispositioned proximate to the user's ear by the attachment member 146 asopposed to being attached to the cord 124 as illustrated in FIG. 1B orbeing integrated with the earbud 100 as illustrated in FIG. 1A.

FIG. 1D is an exemplary diagram of a headset 160 according to oneembodiment of the invention. The headset 160 includes a support member162 that supports a first ear interface 164 and a second ear interface166. The second ear interface 166 can include the activity sensor 110.In one implementation, the activity sensor 110 is integrated within thesecond ear interface 166.

FIG. 1E is an exemplary diagram of an earbud 180 according to oneembodiment of the invention. The ear bud 180 can include an upperportion 182 and a lower portion 184. The upper portion 182 can also bereferred to as the body of the earbud 180. A detachable portion 186 canbe attached or detached from the upper portion 182 via a slot 188provided within the upper portion 182. The detachable portion 186 caninclude the activity sensor 110. In one implementation, when the earbud180 has the detachable portion 186 attached to the upper portion 182 viathe slot 188, the activity sensor 110 provided within the detachableportion 186 is effectively integrated with the earbud 180 and can, forexample, operate as can the earbud 100 illustrated in FIG. 1. In analternative embodiment, the detachable portion could be coupled to thelower portion 184 of the earbud 180.

As previously noted, the headphones, earbuds or headsets can be wired orwireless. In the event that the headphones, earbuds or headsets arewireless, then sensor data captured by the activity sensor 110 can alsobe transmitted wirelessly. Typically, the wireless transmissions arerelatively short range, such as less than 20 feet. Bluetooth is oneexample of short range wireless protocol suitable for use with shortrange wireless data communications.

FIG. 2 is a block diagram of an electronic system 200 according to oneembodiment of the invention. The electronic system 200 includes amonitoring system 202 that monitors physical conditions, such asactivity, associated with a user of the electronic system 200. Themonitoring system 202 can include at least one sensor that capturesmonitored data. The monitored data can be supplied to a processing unit204. The processing unit 204 can pertain to a microprocessor, acontroller, an integrated circuit or other circuitry used to process themonitored data. The processing unit 204 can store to and/or retrievedata from a memory 206. The processing unit 204 can also determine anappropriate output, if any, to be display on a display device 208. Theelectronic system 200 can further include a user input device 210. Theuser input device 210 can, for example, pertain to one or more of: atouchpad, a keypad, a dial, or a button. The electronic system 200 canalso include a battery 212. The battery 212 can allow the electronicsystem 200 to operate as a portable electronic system.

The monitoring system 202 can include at least one sensor. The sensorcan be an activity sensor. In one implementation, the activity sensorcan use at least one accelerometer. The accelerometer can be a one-axisor multiple-axis accelerometer. As an example, when the hearing device214 includes a pair of earbuds, one or both of the earbuds can includeone or more accelerometers. In another implementation, the activitysensor can use a plurality of accelerometers. The sensor can also beother than (or in addition to) an activity sensor, such as apsychological or biometric sensors which could measure temperature,heartbeat, etc. of a user of the monitoring system 202. Since sensorscan be positioned proximate to the head or ear of the user, usefulpsychological or biometric data can be acquired. The sensor can also beother than (or in addition to) an activity sensor, such as a globalpositioning system (GPS) receiver or a proximity sensor.

In one embodiment, such as illustrated in FIG. 2, the monitoring system202 can be provided in or attached to a hearing device 214. The hearingdevice 214 includes at least a speaker 215 (more generally, an audiooutput device) for providing audio sound to a user of the hearing device214. The hearing device 214 can, for example, pertain to a headphone,earbud or headset. In such an embodiment, the balance of the electronicsystem 200 (e.g., the processing unit 204, the memory 206, the displaydevice 208, the user input device 210 and the battery 212) can residewith an electronic device 216. In an alternative embodiment, the hearingdevice 214 can include some additional circuitry. For example, thehearing device 214 could include processing circuitry to at leastpartially process the monitored data from at least one sensor with themonitoring system 202.

The monitoring system 202 can also be used to control or influenceoperation of the electronic device 216. The monitoring system 202 cancouple to the electronic device 216 via at least one wire (e.g., acable) or wirelessly (e.g., Bluetooth). For example, if a wire is usedthe wire can be a dedicated wire or can be a wire that is shared, suchas a cord from the electronic device 216 to a headphone, earbud orheadset. The electronic device 216 can be controlled can be a stationarydevice or a mobile device. As examples, the device being controlled canpertain to a telephone, digital media player, personal digital assistant(PDA), etc.

In one implementation, the monitoring system 202 includes merely the atleast one sensor. In another implementation, the monitoring system 202further includes circuitry used to partially or fully process themonitored data from the at least one sensor.

According to another embodiment of the invention, given that there canbe an activity sensor proximate to a user's ear or head, the activitysensor can be utilized to control an electronic device (e.g., electronicdevice 216). For example, if the electronic device is a mobile mediaplayback device, then the movement of the user's head can be utilized toinvoke commands for the media playback device. For example, moving one'shead in a predetermined manner can be considered as a gesture. In thecase of the media playback device such a gesture can cause play, pause,next, back, skip, volume up, or the volume down. Table provides someexemplary gestures.

Gesture Command Tilt head left Next item forward Tilt head right Nextitem backwards Rotate head right Increase volume Rotate head leftDecrease volume Tilt head forward Play Tilt head backward Pause

To simplify user input gestures and/or processing therefore, a gesturecan be combined with a user input action (e.g., button action). Forexample, if a cord for headphones, earbuds or headsets include an userinput device (e.g., user input device 126), the user input device 126(e.g., button) can be activated (e.g., pressed) while (or immediatelyprior or immediately after) the gesture is being performed. This allowsthe device to understand when it receives a gesture intended to cause auser control of some feature of the electronic device.

More generally, gestures, such as head gestures, can be used as inputsto an electronic device. Sensors (e.g., accelerometer, gyroscope, motionsensor) provided proximate the user's ear or head can be used to detect,pitch, roll and/or yaw of the head, all of which can be potentially usedas inputs to an electronic device. The head gestures can have variousmeanings depending on application. For example, the same head gesturecan initiate a different action in different applications. The sensingused to identify a gesture can be binary or analog. For example, withregards to binary, a head turn may simply change from one state toanother. With regards to analog, the movement itself may impact acontrol function. It should be appreciated that head gestures may beused separately or in combination to provide inputs. The various motionsthat may be detected include, for example: left tilt, right tilt, backand forth left and right tilt, forward tilt, back tilt, back and forthforward and back tilt, left rotation, right rotation, back and forthright and left rotation, swirling the head in a circle in verticalorientation, swirling the head in a circular manner in a horizontalorientation. The motions may also be distinguished or altered as afunction of speed, time, pauses in between, etc. An entire head gesturelanguage may be developed. In one example, a head bobbing can be used ina manner similar to Morse code in order to provide text input commands.Further, “noise” filtering can be provided so as to reduce erroneousdetection of gestures during regular head movements. The variousgestures can cause inputs (e.g., commands) to an electronic device, suchas for an application operating on the electronic device. The inputs canbe user selections, user data inputs, scroll, browse, navigation, cursercontrol, etc.

In one implementation, a scroll, browse or paging action can beinitiated or controlled by one or more head gestures. For example, arotate head or tilt head to right can cause a next item/page action tothe right. Subsequently holding ones head in the tilted position cancause the speed of the action to increase until head returns to normalposition.

In another implementation, a yes Inc input can be provided by a headgesture. For example, if system asks a user of a mobile telephone forinput when the mobile telephone is in use, such as when another callcomes in, the user can be prompted with a screen that asks whether toskip an incoming call or place current call on hold to answer incomingcall. In response, the user could simply reply yes or no as he would innormal conversation. Alternatively, the user could provide one or morehead gestures, e.g., back and forth horizontal head movement for a “no”response or back and forth vertical head movement for a “yes” response.

In another implementation, an up or down movement creates verticalscroll event, whereas left or right movement creates horizontal scrollevent, and further holding ones head in up, down, left or right positioncan increase or accelerate the rate of scrolling until the head is movedback to normal

In another implementation, a head gesture can be used to acknowledgesomething. For example, a simple head tilt, may be used as an entercommand.

In another implementation, moving the head left can request a “forward:action, and moving the head right can request a “back” action, or viceversa, Alternatively, moving the head upward in the vertical directioncan request a “back” action, and moving the head downward in thevertical direction can request a “forward” action.

In another implementation, a left tilt followed by front tilt canrequest a pick/drag/drop upward left direction on screen. A right tiltfollowed by front tilt can request a pick/drag/drop upward rightdirection on screen. A left tilt followed by back tilt can request apick/drag/drop downward left direction on screen. A right tilt followedby back tilt can request a pick/drag/drop downward right direction onscreen.

In another implementation different head positions may be associatedwith different entries or functions. With regard to data entry, thevarious head positions may equate to alpha-numeric characters or userinterface control for selecting or entering alpha-numeric characters.

In another implementation, a number of movements in a sequence (e.g.,successive movements) can signify an entry number or a number of entriesby the user. For example, one movement can signify one entry, or entry#1, two movements can signify two entries or entry #2, etc. A differentgesture or a pause can cause the user input to be finalized.

In still another implementation, small quick discrete movements may havea first meaning while large exaggerated movements may have a secondmeaning.

FIG. 3 is a flow diagram of a head gesture process 300 according to oneembodiment of the invention. The head gesture process 300 can, forexample, be performed by an electronic device having a monitoringsystem, such as the electronic device 216 illustrated above in FIG. 2.

The head gesture process 300 can begin with a decision 302 thatdetermines whether a head motion has been detected. When the decision302 determines that a head motion is not detected, the head gestureprocess 300 can await a head motion. In other words, the head gestureprocess 300 operates or is invoked once a head motion is detected. Ahead motion that is detected can pertain to a head gesture or a randomhead movement of a user. Though filter processing, the head gestureprocess can eliminate many random head motions of a user that are notintended to provide a gesture. Hence, once a head motion is detected, adecision 304 can determines whether the head motion corresponds to agesture candidate.

When the decision 304 determines that the head motion is a gesturecandidate, the head gesture process 300 can attempt 306 to recognize thehead gesture. A decision 308 can determine whether the head motion isable to be recognized as a head gesture. Here the characteristics of thehead motion can be compared with characteristics for a set ofpredetermined head gestures. If the decision 308 determines that thehead motion is able to be recognized as a particular head gesture, anaction associated with the recognized head gesture can be identified310. The action can be a control signal or command for the electronicdevice. Thereafter, the identified action can be performed 312. Afterthe identified action is performed, the head gesture process 300 canend.

On the other hand, if the decision 308 determines that the head motionis not able to be recognized as a particular head gesture, the blocks310 and 312 are bypassed and the head gesture process 300 can end. Also,if the decision 304 determines that the head motion is not a gesturecandidate, the blocks 306-312 are bypassed and the head gesture process300 can end. In these situations, the head motion detected does notresult in a recognized head gesture or an action performed in responseto a recognized head gesture,

Additionally, the electronic device can monitor user actions passivelyand make appropriate decisions, for example, based on user actions orconditions, the electronic device can perform physical monitoring forthe user. Examples of physical monitoring can vary. However, one exampleis that in the electronic device can estimate whether the user is tired,and if so, can induce or motivate the user to continue. As anotherexample, the electronic device can sense when the user is runninguphill, and generate the appropriate motivation for the benefit of theuser. Some examples of motivation for the user are playback of amotivating song, providing encouraging words, increasing playback tempoof a song being played, etc. U.S. Patent Publication No. 2006/0107822,which is hereby incorporated herein by reference, contains additioninformation on synchronized song playback in view of user activity.

In one embodiment, although activity monitoring with headphones, earbudsor headsets can be used to control an electronic device (host device),such as a portable media player, the headphones, earbuds or headsets canoperate separate from an electronic device. For example, the headphones,earbuds or headsets can include the sensor, processing resources and anenergy source (e.g., battery). As one particular usage example, theheadphones, earbuds or headsets can itself determine distance traveledand provide a beep or vibration to the user via the headphones, earbudsor headsets at predetermined distances (e.g., every mile). Theheadphones, earbuds or headsets can be self-actuating based on initialmovement or based on a proximity sensor that knows when the earphone isin the user's ear.

In one embodiment, the portable electronic device can also eitherdirectly support wireless communication with the monitoring system orsensor or indirectly support wireless communications by using anattachable accessory device that provides wireless capability to theportable electronic device. U.S. Patent Publication No. 2007/0270663,which is hereby incorporated herein by reference, contains additioninformation on wireless accessory devices.

In one embodiment, the monitoring system can be used, alone or withanother electronic device (e.g., media playback device), to provideaudio feedback or speech. In one embodiment, the electronic device cansupport speech recognition so as to be capable of being commanded byuser speech commands, alone of in combination with gestures (discussedabove).

In still another embodiment of the invention, the activity sensor beingutilized above can be combined with other sensor data provided by amonitoring system. The advantage for the monitoring system is that theoverall quality of data being received and processed can be increasedthrough use of additional sensors. The presence of the multiple sensorsalso increases the extent to which other characteristics associated withthe user can be monitored and utilized for the benefit of the user. Forexample, these other characteristics associated with the user caninclude form, posture or type sporting activity. Further, in oneembodiment, using such one or more other characteristics (regardless ofhow acquired), type of user activity can be determined. Further, whenused with a digital media player, the type of activity (or moregenerally the user characteristics) can be used to set influence mediaselections for playback by the digital media player.

According to another aspect of the invention, motion and/or directionalsensors can be used to determine the direction of the user's gaze. Oneor more sensors in a user's ear can provide an indication of movementand/or direction that a user is looking or gazing. The sensor can besupplied to an electronic device which can determine the direction theuser is looking or gazing. The electronic device, or applicationsrunning thereon, can make use of the determined direction. For example,the electronic device (or its display screen) can turned on if the useris looking at the electronic device itself and turned off (or placed ina power saving mode) if the user is not looking at the electronicdevice, thereby saving valuable battery power. The direction can also beused in combination with GPS data to allow a device/system to know whata user is looking at.

According to another aspect of the invention, a portable electronicdevice coupled to the monitoring system can monitor, process, presentand manage data captured by one or more sensors. The portable electronicdevice offers a convenient user interface that can be visual and/oraudio based customized to a particular application, user-friendly and/ordynamic. The portable electronic device can pertain to a portable mediaplayer and thus also provide media playback. U.S. Patent Publication No.2007/0271065, which is hereby incorporated herein by reference, containsadditional information on such a portable electronic device.

In one embodiment, the invention is suitable for use in monitoringsports-related data, such as exercise data (e.g., distance, speed,duration, etc.). However, it should be recognized that the invention isnot limited to sports monitoring, but instead is applicable to any typeof monitoring. For example, the monitoring can be any physiologicalmonitoring of a person, who is typically the user of a portableelectronic device. Still further, according to one embodiment, datamonitoring and management can be organized into workouts. A graphicaluser interface that permits user configuration or user selections,presents menus for workout selection, presents workout statusinformation, and provides workout results. A particular or selectedplaylist (i.e., a group of songs) can be played during a workout. U.S.Patent Publication No. 2007/0270663, which is hereby incorporated hereinby reference, contains addition information on physiological monitoring,and U.S. Patent Publication No. 2007/0271065, which is herebyincorporated herein by reference, contains addition information onorganization of workouts.

The various aspects, features, embodiments or implementations of theinvention described above can be used alone or in various combinations.

The many features and advantages of the present invention are apparentfrom the written description. Further, since numerous modifications andchanges will readily occur to those skilled in the art, the inventionshould not be limited to the exact construction and operation asillustrated and described. Hence, all suitable modifications andequivalents may be resorted to as falling within the scope of theinvention.
